Phase 1B Landfill Gas Monitoring Network_Redacted.pdf

This is an aerial map depicting the Salem VAMC CDD Landfill's Landfill Gas Vents and Monitoring Network as of May 2026. The image shows a waste management facility with multiple infrastructure components distributed across the site. The landfill gas management system includes numerous gas vents (indicated by black dots), gas wells (orange triangles), and landfill structure gas monitoring points (yellow star symbols). The site contains a sewer manhole and multiple groundwater monitoring wells labeled LGW-1 through LGW-6A, along with additional monitoring designations (LGW-2B, LGW-4A, LGW-5A, and LGW-5B). Groundwater wells are classified as either upgradient (blue circle) or downgradient (red circle) to the waste management boundary, with one static water level measurement-only location (green circle). Building structures are identified by numbers (#35, #46, #97, #117, #147, and #34), and monitoring wells are labeled with MW designations (MW 1B, MW 2A, MW 3A, MW 4, MW 5, MW 7, and MW 8). The scale indicates 0 to 150 feet, and a north arrow provides directional orientation for the landfill complex.
